ruby-on-rails - Ruby on Rails 教程 - Michael Hartl - 测试 "User when email address is already taken"

Question

我在“用户已使用电子邮件地址时”的测试中遇到问题，这是我运行测试时显示的内容

1) User when email address is already taken
 Failure/Error: user_with_same_email = @user.dup
 NoMethodError:
   private method `initialize_dup' called for #<User:0x007f9710c7c528>
 # ./spec/models/user_spec.rb:78:in `block (3 levels) in <top (required)>'

我没有意识到我将什么定义为私有(private)的，我不能调用。

这里是测试

    describe "when email address is already taken" do
    before do
        user_with_same_email = @user.dup
        user_with_same_email.email = @user.email.upcase
        user_with_same_email.save
    end

    it { should_not be_valid }
end

这里是用户模型

class User < ActiveRecord::Base
  attr_accessible :email, :name, :password, :password_confirmation
  has_secure_password

  has_many :microposts, dependent: :destroy

  before_save { self.email.downcase! }
  before_save :create_remember_token

  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false }

  validates :name, presence: true, length: { maximum: 50}

  validates :password, length: { minimum: 6 }

  validates :password_confirmation, presence: true

  private
  def create_remember_token
    self.remember_token = SecureRandom.urlsafe_base64
  end

end

谢谢

这是带有 ruby​​ 2 的 Rails 3.2.12 中的一个错误。看看这个 https://github.com/rails/rails/issues/9417 .切换到 Rails 3.2.15 应该可以解决您的问题。
